7 '0 all w hjom it may "concern Be it known' that 11, BFOQK-SYKEs, thecity of'Toront0,"in"tl1e county of Yorkifinr the Province of "Ontario,in the Dominion of'Canada, havefinvented certainl'new and usefulImprovements ln' Galendars, and do herebydeclarethat the following is afull, clear, and exact description of sameo j This invention relates tocalendars adapted to forman attachment for a telephone for theconvenience oftelephone users and has therefore for its object toprovide an article of utility of thistype which maybe readily attachedto the usual kind oftelcph'on'ewhile" being capable of use as awalllorgeneral calendar ifso desired, i l

, Further object's are to provide simple and etficient meansforeffecting the securing of i the calendar agalnst, inadvertentdisplace ment when positioned upon a telephone.

Still further objects subsidiary to or resulting from the abbveobjectsor from the con; struction of the calendar as hereinafter de-'scribed will become apparent as the invention is further disclosed.

In carrying the invention into effect I prefer to employ a rotary datedisk suitably inscribed and divided into the various months, said diskbeing located and supported within an outer casing and provided with acentral orifice registering with a central orifice in said casing, theseorifices being of sufficient size to permit the entering thereinto ofthe mouthpiece of the telephone when said calendar is positioned uponsaidphone and means being preferably provided in proximity to saidorifice, to resiliently grip said mouthpiece for the purpose ofpreventing the rotation of said casing about said mouthpiece. Furthermeans may also be employed to secure the said casing against moving inforward direction above the said mouthpiece if thought necessary ordesirable; all of which is more particularly described in and by thefollowing specification, having reference to the accompanying drawing inwhich n i t w a We ile n iar jerscan thaniEig. 1;

Similar, character of reference indicate similarj oarts in the severalfiguresofthe drawing."

Infthe example illustrated is theitrans' mitter' casing of "desk"telephone having the usual 2 and, carrying ftlie detachable mouth-piece3 in the manner well known.

As an article "of utilit'y itis proposed to apply apnendar, preferablyof; that type Figs; 2 and 3 aredrawn to a somewhat.

located in a'jrea dily accessible position.

.i-a'na 5a're front and rear plates forming l iv a a in i cles ns a roty da e dislrhaving the several'months or other m formation printed orotherwise inscribed thereon, the said front plate 4 of the casing 4, 5being suitably orificedas at 7 to permit the viewing of such portion ofsaid disk 6 as a may register with the said orifice 7, the said diskbeing capable of rotation to bring va rious portions of its surface intojuXta-position with said orifice 7.

The casing 4, 5 and the disk 6 are centrally orificed, said orificebeing of suflicient diameter to admit of the passing therethrough of thesmaller end of the saidtelephone mouthpiece, so that when the calendaris located upon a telephone,-as shown in Figs. 1 and 3 of the drawing,the smaller end of said mouthpiece 3 in proximity to the transmittercasing 1 will be accommodated within the said centralorifice of saidcalendar.

It is desirable, but not absolutely necessary, that the said centralorifice shall be of a size in proportion. to the size of said mouthpiecewhereby the same, when in position will frictionally abut against thetubular wall or bushing 8 surrounding said orifice as a preventiveagainst accidental rotary displacing of'the casing of said calendar.

To facilitate the accommodation of the size of said orifice to anyslight variation in the diametrical size of different mouthpieces it maybe preferable to make the said wall inclosing said orifice resilient,such as by thev tapering of said wall toward the rear endthereof andproviding the same with slots or incisions 9 to permit the expansion ofsaid tubular wall when a mouthpiece of sufficient diameter is insertedtherein. The additional compressive effort, in this case, of theresilient tubular wall of said central orifice also locks the said outercasing 4, 5 of the calendar against inadvertent rotation upon thetelephone.

Where the transmitter casing l is provided with a rim 2 as shown in thedrawings, peripheral clips 10 may be resorted to as a means or as anadditional means of securing thecasing 4:, 5 of the calendar tothe'telephone, these clips being preferably integral with one or otherof the component parts of the said calendar casing and extending.rearwardly and inwardly to an extent adapting them to engage with thesaid rim 2 and thereby preventmovement of the said calendar away fromthe face of the said transmitter casing, the said clips also having aradial resiliency whereby they willcontract upon the said rim to anextent sufficient to prevent any undesirable rotary movement of saidcalendar casing.

11 is a slot in the lower edge of the calendar casing to permit accessto the disk 6 for the purpose of adjusting the same.

12 is a ring by which the calendar may Copies of thispatent maybeobtained for be suspended from a hook upon a wall or the like, if it bedesired to use it in this manner.

This invention may be developed under the scope of the following claimswithout departing from the essential feature of the invention and it isdesired that the specification and drawings be read'as merely illus- 2.A device of theclass described, comprising a centrally orificed disk, acasing inclosing said disk, and a bushing on the front part of saidcasing, said bushing ex-f tending rearwardly through the said centralorifice insaid disk, and through the back of said casing for thepurposes specified, said bushing also being of an expanding nature. p rr Signed at the city of.
